A woman, usually of African-American descent, who is perceived as showy or distasteful. Usually she listens to hip-hop songs from artists of dying popularity, wears tight and revealing clothing, pretends to be someone or something she is not, wears unpopular brands of shoes, relies upon child support checks and food stamps for income and food, relies upon moral support from her "girlfriends", and is sexually promiscuous, arrogant and immature.

Man, dat bitch over dere is so ratchet. She got all her girlfriends playin' on her every word like she some prom queen. Damn, she ratchet!

Ratchet is a noun as well as an adjective. As a noun, a ratchet is someone (male or female, of any race) that has no social grace. They do not know how to say things like "please" or "thank you" and are often seen wearing clothes that are either too big or too small. Example: "That ratchet came over here and made a huge mess, then left it for someone else to clean!"

As an adjective, ratchet describes a person's behavior. It does not imply or insinuate a gender, race, or sexual preference. Plainly put, if someone says, "You are ratchet" they are saying you act like a fool, you have no manners, and you are ignorant in all forms of etiquette. A ratchet customer in a bar or restaurant will make ridiculous demands, they will flag a server down 100 times for stupid things, they chew with their mouths open, they make a huge mess on the table, they sit in someone's section for hours without buying anything (they will drink water and suck ice cubes instead), and they won't leave a dime because ratchets are notoriously cheap. They will also pluck one of their own hairs and drop it on their empty plate and then demand a refund for the food they ate.

Don't be ratchet!

Noun: We had to call the police because two ratchets got into a fight.
Adjective: She was at least 250lbs and wearing a pair of yoga pants that said "Bootylicious" across the back. She is ratchet!

Pathetic football player who has some mental issues. Someone who can't exactly process what an average or below average would remotely be able to do. Try's and fails daily. A little thick around the middle. No friends. No life. Watchout for the big package. He may try and use it as a weapon. It's scary to think people like this are alive. Hide yo kids. Hide yo wife. Don't talk to ratchets. Say no to ratchets.
